BRISTOL, ENGLAND - AUGUST 06: A hot air balloon flies over Bristol during a dawn flight on August 6, 2013 in Bristol, England. The early morning flight of over twenty balloons over the city was organised as a curtain raiser for the four-day Bristol International Balloon Fiesta which starts on Thursday. Now in its 35th year, the Bristol International Balloon Fiesta is Europe's largest annual hot air balloon event in the city that is seen by many balloonists as the home of modern ballooning.
